The telephone was invented in the 1870s and continues to be a very important means for people to communicate with each other. The Web by comparison is very recent, but is rapidly becoming a competing communications channel. The convergence of telecommunications and the Web is now bringing the benefits of Web technology to the telephone, enabling Web developers to create applications that can be accessed via any telephone, and allowing people to interact with these applications via speech and telephone keypads. Historically W3C's standardization work on Voice technology of the Voice Browser Working Group was driven by the needs of call center telephony. However, today's mobile devices use not only the visual user interface but also the speech interface for accessing the Web, so the work is now driven by mobile device needs as well. Visual interfaces are very useful for accessing the Web but there are several possible barriers of communication only with the visual interface on small devices, and Voice technology could be a promising solution to the barriers. For example, Voice is available on any kind of phones and in all kinds of languages. Also it requires much less training to use since it is more natural than usual visual user interfaces.
Now the group is concentrating on the SCXML specification. Following the publication of the Candidate Recommendation, substantial comments were received and the group added changes to the normative language for history states and to the algorithm for SCXML interpretation. Furthermore, the algorithm has been changed to informative status. Therefore according to the W3C Process, the group published an updated draft as a Last Call Working Draft.
We are now getting getting important public comments which suggest improvement of the spec, and the editor is working on those coments. Implementations of the spec have been obtained already, but still need an implementation for the XPath Data Model feature.
The group expects to transition directly to Proposed Recommendation once the sufficent implementations are obtained.
There are currently no open groups in this Activity.
This Activity Statement was prepared for TPAC 2014 per section 5 of the W3C Process Document. Generated from group data.
